No signal on monitor computer freezes up

Yes as long as your T6520 comes with at least a 400 watt power supply. It has the required 16x PCI Express slot.

in general the processor won't die easily. check the fun , check capacitors around in mother board.the sign for bad capacitors is that the top of those capacitors exploded or bend...

Hello
Try reseating the video card in the pci slot,remove completly then reinstall.

Also check your monitor video cable for being tight.

Last..Does this card require 24 volts? check for a 4 pin adaptor plug on the card.It may need its own power.

This can be because of virus infection, there are so many applications on your start up and low virtual memory.
But my best suggestion is for you to run a virus scan on your computer so it can detect viruses, worms and malware that you get in surfing the internet or by just sharing files. If this will not work you need to re-install your OS so your computer would be like brand new.

Try continually pressing the F8 key as it starts. You may be able to start it in 'safe mode'.

You haven't got a usb flash drive in one of the usb ports, have you? That can sometimes cause the problem you describe.

Any error messages apperaing on the screen? Don't forget the monitor cable ...

in my opion deep freeze (pige head)is not good progrram .itt creat big problem. we should know well how can be use it. once a time u should reinstale it or formate ur computer,i hae facing many problem from my custmer. -----thanks

I had the same problem, so I switched the Auto Source feature to "Manual" and so far it's working fine for the past 2 days, if I run into the problem again I'll update this message.

On the side panel of your monitor, press the top button to access the menu, scroll down to the setup menu (by pressing the 3rd button down on the panel), press the 4th button down to enter the setup menu, scroll down to "Auto Source", use the 4th button to select, "Auto" & "Manual" are your choices.. press the 2nd button down to select "Manual" then the top button to exit the menu(s).

This monitor is set up to be able to do multi display with the software included. Utilizing both Digital and Analog signals. I'm not using this feature so I'm not sure how switching the Auto Source off will affect the performance of this feature.

Based on your previous troubleshooting, with both built-in video and alternate video card, I'd guess you have a bad mobo. Anything else that was wrong with it (RAM, CPU, etc) and you'd get beep codes.

Sounds like it's time for a replacement board. If the eMachine is out of warranty, it might make more sense just to go ahead and upgrade now, as they are so inexpensive. If you are capable of replacing the board yourself, that would be the cheaper alternative.

Hope this helps - remember to rate (and great troubleshooting, btw!)

Make sure your monitor is plugged in and try again

your lcd need a tech who could help you to repair the power failure.
